[dms-discuss] Raspberry Pi GPIO workshop update

[Bill King]

Some unexpected good news.

I just tested at the library. mDNS does work there and I'm able to connect
via SSH to the test Pi. So if the hostname is set and the
wpa_supplicant.conf file is correct on someone's Pi, they should be able to
log in from a laptop (AS LONG AS mDNS works on their laptop. My Mac works
fine, my Linux machine as issues.)

If mDNS fails the fallback is to log in via the Serial cable and
troubleshoot.

If that fails, the wpa_supp on the Pi's card can be edited on a Linux
machine or otherwise debugged.
